Summer heat can add to the problems faced by people living with type 2 diabetes. And while most people with diabetes are aware that extreme heat poses a danger, they may not always know when to take precautions. Elderly people are at particular risk, but people of all ages with diabetes should be aware of summertime dangers. These include dehydration, heat exhaustion, and foot problems.

DIABETES AND DEHYDRATION

Everyone, regardless of their health status, should make sure they drink enough fluids during the summer. People with type 2 diabetes, however, face an additional challenge because when their blood sugar levels are too high, they may be passing more urine than usual — which means they are losing fluids more quickly.

If you are out and about on a hot summer day, make sure you have enough of these beverages in hand to stay hydrated:

Water
Sugar-free lemonade or other drinks

Also, avoid alcohol and caffeine. Alcohol and caffeinated drinks are usually okay in moderation — but too much of either one can cause you to lose more fluids. And remember to bring along snacks in case your blood sugar drops.

DIABETES AND FOOT HEALTH

Proper foot care is important for people with diabetes. In the heat, your feet can get sweaty, making your socks wet. Make sure your feet are dry and protected when you are outdoors — either with sunscreen or shoes that provide coverage. Check wounds daily. Wounds of a person suffering from diabetes do not heal quickly, sometimes there is a big wound in the middle of the foot, which does not heal easily, for which you should go to the doctor as soon as possible and this treatment is known as diabetic foot ulcer treatment.

DIABETES AND HEAT EXHAUSTION

If you're going to be outside, be alert to these symptoms of heat exhaustion:

Dizziness
Fainting or near-fainting
Excess sweating
Muscle cramping
Cold/ clammy skin
Headaches
Rapid heartbeat

During heat waves and periods of high heat, find air-conditioned places to stay.

DAMAGED DIABETES SUPPLIES

Heat can affect your diabetes supplies too. Insulin is particularly vulnerable, but all medications, glucose meters, and testing strips should be kept in a cool, dry place.

Never leave insulin or other medications in hot cars, direct sunlight, or other extremely hot situations. Use a cooler or insulated lunch bag to keep items cool. Testing strips, meters, and pumps should be kept dry and away from extreme heat. Exposure to intense heat may make them unreliable for later use.

HOW TO COPE WITH SUMMER HEAT

Exercise in a cool place: Staying active is an important part of managing type 2 diabetes. So in the summer months, plan your workout for a location or time of day that is cool, such as:

Early morning
Indoors, with air-conditioning or fans
Water based like swimming
Check blood glucose levels often: Aim for checking four times each day and before you drive.
